They can be worth their weight in gold.

$725 for 30 yd, but you're going over the weight if you fill it. 

I am sorry if my advice isn't what you want to hear, trust me I don't want any of my fellow investors to fail or struggle, it is just the weight of a lot of people's experiences that let me know that trust can be risky with tenants.

They can neutralize what has seeped into the concrete without paint, which will require future upkeep.

Any time one of us is by the house for a maintenance or service request we do a 'look-see' general inspection, which is usually: floors, under sinks, furnace filter, and general upkeep.

Can anyone refer a local person who may be interested in the lawn care/snow removal upkeep that it requires.

@Kyle DutsonMost people budget 5%-10% for capital expenditures(it can be more or less during a year but thats the average).The age of the house may dictate the number you use - Older homes require more upkeep than newer homesQuality of tenants - Better tenants will take care of home better and require lessdate of capital expenditures done by seller - Permits are usually required when there are big repairs done to a house.

People here are as nice as you would find anywhere, and generally like to get along rather than cause a lot of trouble, and as someone that grew up in NJ that's worth it's weight in gold.

My grandmother has her own stresses and doesnt have time to put energy into the upkeep either, so shes looking to sell everything. 

I would recommend cutting them out most likely unless, for your market, you know for sure they are earning their weight.
